Freeze odds, by date

OddsLast spring freeze afterFirst fall freeze before
9 years in 10Mar 31Nov 5
Median — 1 year in 2Apr 15Oct 26
1 year in 10May 4Oct 13

The top row is the risky edge: in 9 years of 10 a spring freeze still comes after it, so tender transplants set out then need cover. The bottom row is the cautious date — only 1 year in 10 freezes after it — and the one to plan uncovered tender transplants against. Freeze-free season: 193 days median, at least 170 in 9 years of 10, at least 214 days in 1 year of 10. NOAA ranks season length year by year, so it is not the gap between two rows above. A hard freeze (28 °F) has a median last date of Apr 2 and first of Nov 3.
